Steven Croft explores the natural beauty in his birth-state of Georgia, where his poems bring the reader to the lush coastal landscapes of the Barrier Islands and the nurturing comforts of Southern living.

Biogeochemistry may be defined as the science that combines biological and chemical perspectives for the examination of the Earth¿s surface, including the relations between the biosphere, lithosphere, atmosphere, and hydrosphere. Biogeochemistry is a comparatively recently developed science, that incorporates scientific knowledge and findings, research methodologies, and models linking the biological, chemical, and earth sciences. Therefore, while it is a definitive science with a strong theoretical core, it is also dynamically and broadly interlinked with other sciences. This book examines the complex science of biogeochemistry from a novel perspective, examining its comparatively recent development, while also emphasizing its interlinked relationship with the earth sciences (including the complementary science of geochemistry), the geographical sciences (biogeography, oceanography, geomatics, earth systems science), the biological sciences (ecology, wildlife studies, biological aspects of environmental sciences) and the chemical sciences (including environmental chemistry and pollution). The book covers cutting-edge topics on the science of biogeochemistry, examining its development, structure, interdisciplinary, multidisciplinary, and transdisciplinary relations, and the future of the current complex knowledge systems, especially in the context of technological, developments, and the computer and data fields.

This book considers the meaning of the term, considers the value and characteristics of Google Earth, and discusses the main driving forces of landscape change. Google Earth provides a means whereby one can identify changes in the landscapes of Earth over recent decades. This has been a time of great human activity, and landscapes have been transformed as a result of such factors as land use and land-cover change, climate change, the intensive harnessing of new energy sources, population pressures, and globalization. Many geologists now believe that the whole Earth System is being changed and that there is thus a need to introduce the concept of the Anthropocene. It then looks at specific landscape types, including rivers, coasts, lakes, deserts, tundra, and glaciers.

This book represents the latest research on urban forestry in a Malaysian context. It demonstrates that urban forestry is concerned not only with environmental enhancement, but also other aspects, such as recreation, health and well-being, and government policies. This edited collection provides a comprehensive overview of urban forestry studies from various researchers in Malaysia, and includes rich historical perspectives of urban forestry in the country. It also tackles related issues in policy. The greening of urban Malaysia in the 1970s focused primarily on beautification and was primarily the province of horticulturists, landscapers, nursery workers, town planners, and architects, with negligible inputs from foresters, particularly urban foresters. Perhaps for that reason, the term "e;landscaping"e; has been used more widely than "e;urban forestry"e; by government and private institutions, politicians, stakeholders, academicians, and the public. Nevertheless, the authors show that the concept of urban forestry is not new for developing countries such as Malaysia, where urbanization is increasing at a rapid rate. The book unpacks this demographic shift from a predominantly rural to a principally urban society. As the only unified body of work on urban forestry and arboricultural studies in Malaysia, this volume presents an important interdisciplinary reference for students, researchers, and scholars in physical geography, forestry and urban forestry, arboriculture and landscape architecture, both in Malaysia, and in other developing urbanizing countries, particularly in Southeast Asia. It is also an important resource for those working in environmental policy and practice, excavating the vital connection between the environment and well-being.

Young children will love bringing to life these amazing images of Scotland's coats and seashore by brushing with water to reveal colour. Very short captions (c. 10 words) describe the various scenes. Just dip the brush (included with the book) in water and apply directly to the page to bring the illustrations to vibrant life.

This book comprehensively discusses the role that non-state actors play in the Arctic and assesses the normative role of these actors. Beyond any organised forum, there are actors that have a significant impact on the way the Arctic is developed, adjudicated, managed, perceived, presented and represented. This book complements the literature on non-state actors in international law and international security, world politics and international relations and provides a geographical account of their role for the Arctic. The book content is not limited to a specific discipline, but takes into account different approaches to the topic. This means that it contains three types of contributions: research articles, shorter research notes and commentaries. While the research articles constitute the main body of the work, it is also the research notes which provide an insight into issues related to the topic of the book.

This book addresses the various factors affecting fluvial systems, the processes governing them, system responses arising from human-nature interventions, and geospatial and geo-ecological modeling to understand system behaviour better and restore degraded ecosystems around the globe. Thanks to their hydrological and agro-ecological advantages, humans have settled along riverbanks since the dawn of civilization. Thus, the ancient "e;ecumene"e; (settlements) were located near major rivers worldwide. This legacy of river-based civilizations continues to this day in many forms. However, in the course of the 'Anthropocene' era, countless fluvial systems have been altered by human interventions in the form of large-scale dams and barrages, changes in land use and land cover, road-stream crossings, mining of sand and gravel, mushrooming of brickfield, expansion of modern agriculture, industrial growth, and urbanization. Thus, the present-day development pattern threatens fluvial systems, especially riverine morphology and ecosystems. In brief, human-induced morphological changes, water pollution, eutrophication, and related damages to aquatic organisms are the major threats to fluvial systems. Thus, maintaining the 'environmental flow' of the world's major rivers to preserve the proper functioning of riverine ecosystems and promote sustainable development is a global challenge.

The book presents the results of a doctoral thesis conducted under the supervision of two international governmental universities in Egypt and the USA. This book is very important for specialists in the field of Physical Geography with concentration of Geographic Information Science and Remote Sensing techniques for Coastal Hazard Assessment. It deals with coastal hazards and disasters using unique techniques and methods, such as Coastline Change Detection, Sea-Level Rise Modeling and Future Predication, Coastal Erosion Hazard Mapping, and Coastal Vulnerability Index. The integration of geospatial technologies that applied accurately in this book especially for the coastal hazard mitigation and protection devise evaluation makes it very helpful for researchers and academics, as well as for coastal and civil engineers.

After plans were announced for multiple dams in Mongolia's Selenge River watershed, award-winning author and veteran flyfishing guide Peter W. Fong was spurred to learn more about this remarkable ecosystem. On a first-ever scientific expedition from the headwaters of the Selenge to Russia's Lake Baikal, he and an international team traveled more than 1,500 kilometers by horse, camel, kayak, and rowboat through one of the world's most rugged regions and a last, best stronghold for the planet's largest salmonid: the taimen.¿Fong's account of this dramatic journey tells a passionate yet nuanced story of the Selenge River and its tributaries. About the fish and wildlife that call the river home. About the human history of the region, from the Bronze Age to the fall of the Soviet Union. About the people who live in the basin now-from nomadic herders to construction engineers-and their attitudes toward development and conservation. About the old gods and legends that haunt the mountains. And about the disparate possible futures for one of the most starkly beautiful places on earth.

Mining and geological survey work in Jamaica goes back several hundred years and was initiated by the Europeans when they colonized the Island. The year 2019 marked 160 years since the first Government-commissioned Geological Survey of Jamaica. This is one of the oldest survey activity of this type in the World! This book seeks to commemorate this heritage. It is one of the first books of its kind examining the evolution of the mineral sector and geological survey work of Jamaica, set in the framework of the Country's history of over 500 years. The Reader will explore a relatively unfamiliar side of the Country's development, linked to popular historical stories that shaped the Nation. The information presented are mostly documented in dated academic literature that are not gauged for a wide audience. This book however, aims to make this information accessible for a wider readership such as students, amateur scientist, non-professionals or anyone who wishes to learn about the rich history and heritage, and the contributions to national development from Europe and much later, North America.

In this thrilling work--a blend of history, science, nature writing, and environmentalism--acclaimed writer James Bradley plunges into the unknown to explore the deepest recesses of the natural world.Seventy-one percent of the earth's surface is ocean. These waters created, shaped, and continue to sustain not just human life, but all life on Planet Earth, and perhaps beyond it. They serve as the stage for our cultural history--driving human development from evolution through exploration, colonialism, and the modern era of global leisure and trade. They are also the harbingers of the future--much of life on Earth cannot survive if sea levels are too low or too high, temperatures too cold or too warm. Our oceans are vast spaces of immense wonder and beauty, and our relationship to them is innate and awe inspired.Deep Water is both a lyrically written personal meditation and an intriguing wide-ranging reported epic that reckons with our complex connection to the seas. It is a story shaped by tidal movements and deep currents, lit by the insights of philosophers, scientists, artists and other great minds. Bradley takes readers from the atomic creation of the oceans, to the wonders within, such as fish migrations guided by electromagnetic sensing. He describes the impacts of human population shifts by boat andspeaks directly and uncompromisingly to the environmental catastrophe that is already impacting our lives. It is also a celebration of the ocean's glories and the extraordinary efforts of the scientists and researchers who are unlocking its secrets. These myriad strands are woven together into a tapestry of life that captures not only our relationship with the planet, but our past, and perhaps most importantly, what lies ahead for us.A brilliant blend of Robert MacFarlane's Underland, Susan Casey's The Underworld, and Simon Winchester's Pacific and The Atlantic, Deep Water taps into the essence of our plant and who we are.

This book focuses on regions for which until now the geomorphology was very poorly studied and relatively unknown. Nevertheless, the landforms and landscapes of the Horn of Africa are highly attractive, diverse and in a few cases unique, since they span very different environments, from highland plateaus and mountains to lowlands (even below sea level) and coastlines with a high degree of diversity and from monsoon to arid climate conditions.  The main topics addressed in the book include the links between the geological evolution and the current large scale geomorphology of the Horn of Africa; the large differences between the highlands and lowlands climate, river hydrology and their variation through time within a climate change perspective. This part of the world was home of the very first hominids. The landscape in which they lived and evolved throughout the Pleistocene is described in comparison with the arid and inhospitable, though immensely scenic, environment of today. Perennial and ephemeral rivers with very different morphology, processes, and hydrology drain the area, and, in combination with the past and recent uplift, substantially contributed to provide the region with peculiar landscapes and landforms. Long lasting weathering and erosion processes result in a typical inselberg landscape such as the Bur region, or the currently exposed flatland of old peneplain surfaces. Their changes through time, induced by both natural and anthropogenic factors, are addressed by a couple of case studies. Though the region has few inhabitants, they had to struggle to find their livelihood in a land that offers poor resources. This resulted in landscape change and land degradation. Examples of human impact on the landscape are presented at different scales.  This book provides readers interested in geography and geomorphology with essential scientific and educational information on the Landscapes and Landforms of Eritrea, Djibouti and Somalia through simple, though scientifically, rigorous texts illustrated with several color maps and photos. One main prerogative of this book is therefore to give an insight into a region of the world where, for geographical and historical constraints, geomorphological investigation was very limited, thus enriching its intrinsic informative value.

This book discusses plant invasions and environmental impacts on the Himalayas through a novel procedure, and helps to understand the influences of climate, physiography, soil, and disturbance on plant richness in mountain systems. Assessing invasion risks to mountain space under future climate change scenarios is highly significant for appropriate preparedness, and this book details analytical and modeling techniques to assess the conditions of mountain ecosystem and ecology to better inform our preparation for future environmental challenges. The book presents the state-of-the-art understanding of the species-environment relationships in a global biodiversity hotspot, relatively unexplored areas for the Himalayan life-form richness. The book provides not only the academic but also the professional community and policymakers a review and update on modeling applications for determining interactions of the plant species with the environment of a subtropical mountain ecosystem across a climatic gradient. Currently, there is no book in the market addressing the implementation and applications of modeling in the Himalayan plant and environment continuum, and most of the existing books cover the species richness pattern along the elevation gradient and basic ethnobotanical features of a mountain system. Since the book covers the applications of novel methods and modeling for ecological analysis of mountain ecosystems, it will also be significant for the professional market. Therefore, the book aims to fill the gap between scientists and professionals in the use of modeling strategies to monitor biodiversity in mountain systems for the formulation of conservation, adaptation, and mitigation principles.

Starting from concrete examples in Geomorphology, this comprehensive textbook explains to graduate and postgraduate students, point-cloud data technology and associated methods from acquisition to final-product generation. In the last few decades, Geo-sciences have experienced a paradigm shift from the challenge of collecting enough data to the need of creating new processing tools that can handle the billions of data. This shift has come to Geomorphology with the increasing use of surface-pointclouds obtained from photogrammetry, laser scanners and processed by specialist software, and it is thus necessary for the next generation of geomorphologist to be fluent in these technologies. Consequently, this book explains from concrete examples how to use pointcloud technologies, from data collection to processing and final product generation. The philosophy of this book relies on two principles, first: you do not have to be a tech-wizard to use pointcloud technologies, allowing the you to bring back the focus on your science; second pointcloud methods can be affordable, therefore the book provide a set of worked-examples in the different geomorphological environments using open source software and R and Python code samples. The book can be used as a textbook in a geomorphology, geology, physical geography, Sabo-sciences and engineering class, as well as a companion for the more seasoned scientist who wants to solve specific problems.

This book describes Sicily's unique and varied karst features, discussing the notable geographical areas, their lithology and genesis and, in a number of cases, their value as geosites to be preserved for scientific or tourism purposes. The rich variety of Meso-Cenozoic outcropping rocks in Sicily make the island highly significant in terms of the geological history of the Mediterranean area.The soluble rocks (limestones and gypsum), widely present on the island, play an important role in shaping and continuously altering the landscape, both in the reliefs with spectacular fluviokarst cayons and suggestive gorges, and below ground where there is a wide range of speleogenically and speleologically important caves.
